Interesting. That's also how I felt the first time I ever used Twilio, having come from a background including telephony (including wrestling Asterisk). I can easily tell Fred has also been exposed to the hellish nightmare of telephony in his past at some point. You can't really imagine just how bad it used to be, even with the Asterisk project. For example I have a fairly large library of computer books (perhaps five or six shelves) in my office ("laboratory"). The thickest book in that place by far is the Asterisk animal book from O'Reilly. The next thickest book is Sendmail's animal book. Twilio really did do something totally amazing.
